PETER PACHTER, OF CHICAGO, ILLINOIS.

TIPPING AND WRAPPING MACHINE.

Application filed January 6, .1919. Serial No. 269,832. A

To aZZ whom it mayconcern:

Be it known that 1, PETER PACHTER, a citizen of .the United States, and a resident of Chicago, in the county of Cook and State 5 of Illinois, have invented .certain new and useful Improvements in Tipping and VVrapping Machines, of which the following is a description reference being had to the accompanying drawings, which form a part of 10 my specification.

My invention relates to a machine for introducing or inserting the inserts or what are known as tips on the signatures of a book :or pamphlet prior to the binding of the signatures, which are to constitute the book or pamphlet, in the binding machine;

the object being to provide a machine whereby the signatures and the tips or inserts ware automatically brought into proper relation and automatically supplied with ad liesive substance; the signatures and the tips or inserts being subjected to proper pressure subsequent to being brought into juxtaposition, after which they are dis charged into-a suitable hopper.

Another object of the invention is-to provide a construction whereby pamphlets or magazines will be automatically rolled and Wrapped for mailing purposes and automatically discharged; the invention contemplating a construction which maybe used as a tipping or inserting machine and as a wrapping machine; the {wrapping mechanism being adapted to operate in conjunction with the tipping or inserting mechanism or separately, as will be more fully COIIlpIehGIlClGClfIOHl the following detailed description of the drawings, wherein Figure l is a side elevation of thetip -insorting end of my improved machine.

Figure 7 is {a detai-lview in se ction.on-.-the line 77 of Figure 3, showing the ends of the power-imparting and cylinder carrying shafts. y

Figure 8 is a detail view in section ,of ,a signature and tip feeding member.

In the specification of the invention, I shall first proceed with a description of what has been termed the tipping ,or gin;

serting mechanism whereby the signatures and tips, are brought into properrelatioh or juxtaposition prior to (the delivery of' the signatures ito suitable binding machinery in which the respective signaturesare I'tO- stapled or otherwise suitably bound gether.

In the specific illustration .of the invention, it comprises .a suitable frame composed of the standards "20, ofsuitable; for,

nlittlOl'iElllClllGlgll't and spaced apart,:a'si'iior.e clearly shown in ;Figure"2 so as to support the operating mechanisms later to be de scribed. The frame of the machine isshown provided with transversely disposed members, as at 21, see Figure -1 on opposite ends whereof are supported suitable racks or holding elements 22' and 23 ;=the racks being shown similar inconstruction andvcompris ing a suitable frame open atathe tops and 22 and 'thetip's or'inserts in .raclr f23,ito

slide toward the inner-ends; of the iracks as the signatures and tips are successively withdrawn from the racks. The rackss22 and 23 are formed so as to maintain-the sig- I natures and tips in vertical position or upright on edge as shown-inlFigurel; the rack 22being provided with sign atures '26 to which the tips or inserts 27, contained in rack 23, are -'to be -attach'ed=throughthe operation of the machinei The cross-members 0f the frameare provide'd with suitable bearings for the ends of 1. Each shaft hasa cylinder or drum se-I curedthereto I as shown atj30 and 31 in Figure 1; thecylinders being preferably"of somewhat skeleton form and keyed to their respective shafts, as shown in Figure 2; that is, the cylinders are formed with circumferential openings or spaces for the passage and operation of gripper fingers or elements shown at 32, rigidly secured to rotatable rods 33, suitably mounted within the circumferential members 34: of the cylinders 30 and 31; the rods 33 being secured adja cent the perimeters of the cylinders as shown in Figures 2 and 4.

At points coincident with the tips of the grippers 32, namely in theoscillatory paths of the grippers, the circumferential members 34: of the cylinders are formed or pro vided with laterally extending lugs or projections 35, see Figure 4, adapted to be en-- gaged by the fingers or grippers 32 when the latter are tripped or actuated by means of the tripping mechanism which comprises a tappet member or star-wheel 36, preferably eccentrically mounted on the end of each rotatable rod 33, see Figures 1 and 4. In the particular exemplification, the cylinders 30 and 31 are each provided with a pair of rotatable rods 33 having one or more grippers 32; the rods being arranged at diametrically opposite points, as shown in Figure 4:, thus enabling a half revolution of the cylinders to carry and transpose a signature or tip as the case may be.

The number of grippers and their disposi- .tion about the cylinders, it will be understood, may be altered, commensurate with the size of the cylinders and signatures and inserts" or tips, as will be readily understood.

The position of the grippers, namely either in gripping or non-gripping position, is maintained by means of aspring-com trolled rod 37 which is pivoted at 38, to the tappet member 36, while the other end is freely slidable through an aperture in the web 39 formed integral with a pair of spokes of the cylinders, see Figure 4:. The rod 37 is encircled by a suitable spring 40, one end whereof bears against the web 39, while the other end bears against the shouldered end or head of the rod, so that the member 36 will be under constant pressure, and maintain it in adjusted position; the pivotal connection of rod 37 with the member 36 and the mounting of the latter on rod 33, are such that the spring 40 will tend to maintain the tilted position of the element 36 and therefore of the rod 33 on which the grippers 32 are mounted. At suit-able points on the frame of the machine, I provide extensions or lugs 41 and 42 which project into the paths of the members 36 so as to engage the latter when the cylinder has rotated a predetermined degree. As is apparent from Figure 4;, the lug 41, at the right in said figure, is so arranged that it will be engaged by the teeth or projections on the short end of member 36 during the revolution of the cylinder 31 (it being understood that the cylinder 31 to the right in Figure i is adapted to revolve in counter-clockwise direction) causing the member 36 and rod 33 to rotate in such direction as to induce grippers 32 to be moved into closed or gripping position so as to grip the edge of the sheet or tip indicated at A in Figure 4.

It is apparent that member 36 may be swung or rotated through the arc of a circle by reason of the sliding relation of rod 37 with web 39; during which operation the spring 40 will be compressed until the end of the rod 37 which is pivoted to member 36, has been moved beyond dead center, that is into a position tangential to the axis of member 36, when the action of spring 40 will place the member 36, and therefore also grippers 32, under tension, thus causing the grippers 32 to firmly hold the sheet as shown in Figure 4.

The continued rotation of the cylinder 31 (the rotation being in counter-clockwise direction as previously stated) will bring the grippers carrying sheet or insert A, to the diametrically opposite point where the long pointed end of the gripper-controlling member 36 will be engaged by the projection or lug 42. The engagement of member 36 with lug 42 will cause the member 36 to rotate about lug 42 during rotation of the cylinder.

The rotation of member 36 about lug 4E2 will cause rod 33 to also rotate in a direction which will induce grippers 32 to oscillate out of gripping position and thereby release the sheet A. This position will maintain until the cylinder has revolved a degree sufficient to again bring the advanced end of member 36 into striking engagement with lug ll and thereby induce a movement of grippers 32 into gripping position and therefore into contact with the edge of another sheet or insert as previously described.

The cylinder 30 is substantially identical with the cylinder 31 just described; except, of course, that the cylinder 30 is caused to rotate in the opposite or clockwise direction.

This cylinder 30 is also shown provided with i a pair of gripper elements disposed at diametrically opposite points; the gripper elements also comprising the tappet members 36 adapted to be actuated by the strikers or lugs and The grippers on the left side of this cylinder 30 have just moved beyond the moment of tripping; namely, the member '36 has just rotated about lug 43, during which rotation of member -36 the grippers were caused to open. In other words, the cylinder 30 in Figure 4 has just been brought to a position where the grippers at the left of cylinder 30 have been recharged with a sheet or signature, as the case may be, in a manner similar to cylinder 31 and its grippers shown at the right hand side of the figure.

On the other hand, the grippers on the cylinder 30, which have been brought into juxtaposition with cylinder 31, have been brought to a position where the member 36 has rotated about the lug or striker 44, during which action the grippers were caused to open and release the sheet or signature, at a moment substantially simultaneously with the releasing action of the grippers on the adjacent cylinder 31; that is to say, the grippers, on the two cylinders, which have been brought into juxtaposition through the rotation of the two cylinders, have both been caused to release the sheets carried thereby; the cylinders being so arranged that the sheets carried byboth cylinders will be forced into intimate relation with each other.

In the exemplification of the invention as disclosed in Figure 1, the cylinder 30 rotates in clockwise direction and is adapted to receive the sheets or signatures which have been stacked in rack 22; while the cylinder 81 rotates in counter-clockwise direction and is adapted to receive the sheets or tips which have been stacked in rack 23, with the result that one signature and one tip will be brought into contact with each other during each half revolution of the two cylinders.

In order to bring the upper edges of a 1 sheet or signature and a tip or insert into proper position, namely into intimate relation with the respective cylinders where the edges may be grasped by the grippers, 1 provide means comprising suitable suction members or fingers 45 shown in dotted lines in Figure 1 and in detail in Figure 8. These members or fingers 45 are suitably pivoted, as at 46, on the frame of the machine; and are provided with a minute longitudinal passage which terminates at the free end or tip of the fingers 45 in a flared or cupshaped orifice 47 which is adapted to extend fiush with the adjacent sheet in the racks 22 The longitudinal passage in the finger or member 45 at the opposite end terminates in a nipple or boss 48on the side of finger 45 atasuitable point intermediate of its ends, as clearly shown in Figure 8. The nipple or boss 48 is adapted to receive the end of a suitable tube as shown in dotted lines at 49 in Figure 1; and this tube 49 at its other end is secured to suitable piping or air-line branch 50, which leads upwardly and is connected to a main line or pipe provided with valve '51; said main line or pipe leading to a suitable suction pump 52, see Figures 1 and 2. As shown in Figure 1, both sides of the machine are provided with a suction tip or finger 45, connected by means of branch lines 50, 50 with the suction pump 52. a

The suction tips or fingers 45, atboth sides of the machine are similarly oscillated on their pivot points 46 by the following described mechanism.

The shafts 28 and 29 of cylinders 30 and 31 are each provided with a cam 53, see Figure 4, similarly disposed so as to operate at the same moment. Suitably pivoted on the frame of the machine at the points 54 and 55 are a pair of bell-crank levers 56 and 57 (see Figures 1 and 4) the inner ends whereof are each provided with a roller 58 adapted to ride on the respective cams 53; while the opposite end of the bell-cranklever 56 rods 59 and 60 each have a spring 61 con nected thereto, while the opposite ends of the springs are suitably connected to the frame of the machine or to some stationary element; the springs 61, 61 being adapted to exert a constant pull on their respective links, and therefore also on the bell crank levers, in a direction which will maintain the inner or roller-supplied ends of the bellcrank levers in constant contact with the cams 53: such action consequently also in ducing the links or rods 59 and 60 to force their respective suction fingers or tips outward toward the racks 22 and 23, respectively, when the cams 53 have passed beyond the inner or roller-supplied ends of the bell-crank levers.

The cams 53 are so formed and arranged on the shafts 28 and 29 that thebell-crank levers 56 and 57 will be actuated against the action of the springs 61 during each.

half revolution of the cylinders, at a pe riod in advance of themoment when the grippers of the respective cylinders reach the upper edges of the stacked sheets in the racks 22 and As a vacuum or suction is setup in the fingers or tips 45 through the action of pump 52, the inward movement of the free ends of fingers 45, induced by the cam 53, will cause the upper edge of the adjacent sheet 'in each rack 22 and 23 of springs'61 after the cams 53 have moyed' fill beyond the inner ends of the bell-crank levers; in other words the fingers or tips 45 are forced outwardly into contact with a succeeding sheet at intervals in the rotation of the cylinders when the respective grippers 32 are disposed intermediate of their points of location shown in Figure 4.

One shaft, for example shaft 28, is also shown provided with another cam or eccentric 62 (see Figures 2 and 7 which is surrounded by an eccentric or cam band 63 which is provided with a rod 64 pivotally connected with the piston 65 of pump 52; the cam or eccentric 62 being so formed that the piston 65 in pump 52 will be actuated or given an induction stroke at least twice for each complete revolution of the cylinders, in order that suction may be setup in the fingers 45 at both sides of the machine in advance of the periods when the grippers are brought into position adjacent the upper edges of the stacked sheets in racks 22 and 23.

The frame of the machine at a suitable point, as for example above the cylinder 31. as shown in Figure 1, is provided with a glue or paste receptacle 66, provided with a rotatable roller 67, arranged to receive glue or paste from the receptacle 66. At a point intermediate of roller 67 and the cylinder 31, I rotatably mount a wiper element 68 which is adapted to wipe across or slightly contact with the perimeter of roller 67 and thereby be charged with a small quantity of glue or paste throughout the longitudinal margin thereof. The wiper element 68 is so disposed that the tip or longitudinal edge thereof will also slightly contact with the sheet carried by the cylinder 31; the rotation of element 68 is so timed, relative to the rotation of the cylinder 31, that element 68 will merely contact with one of the longitudinal edges of the sheet carried bythe cylinder, so that when said edge of the sheet is brought into contact, through the continued revolution of the cylinders, with the sheet or signature carried by adjacent cylinder 30, the firs mentioned sheet on cylinder 31 will be caused to adhere to the sheet carried by cylinder 30.

At a suitable point beneath the point where the two cylinders and 31 are in juxtaposed relation, I provide a pair of compressionrollers 69, 69, see Figures 1 and 2. The rollers are rotatably mounted in the frame of the machine; being driven by means of an idler 70 which is disposed intermediate of one of the rollers 69 and the gearing of cylinder 31 for example, see Figure 1. The arrangement of rollers 69, as shown in the drawings, causes the rollers to rotate in opposite directions and the relation of the rollers to each other is such that the signature and tip or insert which have been brought into glued contact with each other, will be placed under compression before they are discharged into a receiving hopper or trough shown at 71 in Figures 1 and 2 and disposed transversely of the machine beneath the cylinders 30 and 31 and compression rollers 69.

The trough or hopper 71 consists'of a suitable frame having two upwardly diverging sides as shown in Figure 2, so that the discharged signature with its tip or insert will be held upright; the trough being mounted on the frame of the machine by means of suitable brackets 72, as shown in Figure l; the brackets being preferably adjustably and removably secured in place, as shown. The trough 71 is provided with a slot disposed lengthwise in the bottom thereof, see Figure 2, for the passage of an upwardly disposed control member or follower 7 whereby the signatures and tips will be alternately forced toward opposite sides of the trough, to be gathered up by an operator for delivery to the binding machine. The follower or control member 78 is mounted on a rod 74: which is slidingly mounted in brackets 75 secured to the underside of the trough as shown in Figure 1. One end of rod 74 is pivotally connected to a link 76 which in turn is pivotally secured to an arm 77 which is secured against independent rotation 011 a rotatable shaft 78, suitably mounted in the frame of the machine, see Figures 1 and 2.

The shaft 7 8, also has a second arm 79' keyed or otherwise secured thereto and disposed in a direction perpendicular to the direction of arm 77, see Figure 1. The free or outer end of arm 79 has a reach rod 80 pivotally secured thereto, while the upper'end f the rod 80 is secured to a strap or band 81 (see Figure 4) which is disposed about an eccentric 82 mounted on shaft 28.

With this construction, it is apparent that during each revolution of shaft 28, the rod 80, by reason of eccentric strap 81, encircling eccentric 82, is caused to reciprocate; and this reciprocation of rod 80 will cause arm 79 to be oscillated, thereby rocking shaft 78 in a manner which will cause arm 'ZZ-to be oscillated so as to induce follower member 73 to be reciprocated through the medium of link 76 and rod 74. With this arrangement and operation, the follower 7 3 will alternately be moved to opposite sides of the path of the signatures which are discharging into the hopper or trough, so that successive signatures will be automatically forced to opposite ends of the hopper or trough 71.

The shaft 29, in the exemplication illus trated, has its ends mounted in suitable bearings arranged on cross-members of the ma chine-frame, pamely at one end of the machine and at the intermediate point or upright member of the frame, as shown in.

Fi'gu keyed to shaft 29, I also show a gear83 keyed to the shaft at one end of the cyl- -inder (see Figure 2). This gear 83 inturn mesheswith a pinion 84e-keyed to the shaft 85 on which the wiper element 68is secured;

the shaft 85 having suitable bearings at its ends in the frame of the machine, (see Figure 2). caused to rotate when the tip carrying cylinder 31 is rotated; i

One end of shaft 28is mounted in suitable hearings in the frame of the machine, while the other end is supported by a yoke. or bracket 86 which. is secured to the'intermediate members of the frame, as more clearly shown in Figure2.

The end of a. suitable control rod 88. The clutch 87 is adapted to provide operative relation between shaft 28 and a pulley 89 which is loosely mounted on shaft 28; the pulley,

being shown driven by means ofbelt.90, which in turn is driven by means of' motor 91;.

Shaft 281is provided with a gear 92. which. meshes with a gear 83. onv shaft 29, thus causing positive rotation of' shaft 29 and cylinder 31 in. a direction opposite to that of shaft 28 and cylinder 30.

Shaft 29 is provided with'the gear 83. which meshes with the pinion 84con wiper element or shaft '85 as previously described; so that the various elements of the. tip or inserting mechanism of the machine are all driven from the shaft 28 which'fis driven by motor 91 and belt 90.

. he operation of this portion of my improved machine is as follows :-the signatures or book-sections to each of" which the tip or insert is to be applied, are set up! on end in the rack 22 as shown in Figure 1; while the tips or inserts are set upon edge in the rack 23. The machinemay then be set in motion by shifting clutch 87, through the medium of lever 88, in order that power can be transmitted from motor 9l to shaft 28. Rotation of shaft 28 likewise causes shaft 29 and its cylinder 31 to:rotate and" transmit power .tothe various correlated shafts 28 and 29. As the upper edges of addition tocylinder 31 being/ Wiper element 68 is. therefore shaft 28 which extends. through bracket or. yoke.86'aisprovidedwitha clutch 87 slidably keyed thereon (see Figure 7); the clutch being operated. by

the signatures and tipsare drawn by the fingers 45towardthexperlm'eters ofcyl-f inders 30 ,and 31 a. set' of grippers oneach cylinderwill have been brought: into oper atlng position, thus causing a slgnature to be taken by cylinder. 3Qtandia tipiito .be

takenby cylinder 31. During the rotation. of. the cylinders with the signature and tip,- respectively, the. wiper element 68 has been madeto rotate sufficiently tohave wipedaglue .or paste ofl'fof roller v67 andapplied-it to the. margin ,oredge of. the. tip.

carried by cylinder, 31, so that when. the

signature, carriediby cylinder 30 and] the tip are brought into juxtapositionithrough continued rotation of'the cylinders, the tip willibe caused to adhere to the Tsign-atureand with it be made. to pass" between the compression rollers '69,. which are driven from. cylinder 31 by means of anlidlenw70. The, signatures anduttips are'thusisuccessively brought into contactv with each" other, and fed into the hopper 71, where they are. alternately forced toward! opposite ends of the. hopperflby means.- of' the;

follower element '73 which is operated. or

made to reciprocate in. the hopper by means of; the rod 80, eccentric strap; 81 disposed about eccentric 82 on shaft. 28: and the. links scribed; y i

I shall nowv describe. the construction or. arms79, 77, 76 and Has previously .'de-

and operation of the other portion of my improved; machine, namely the pamphlet rolling. wrapping, mechanism and: which is illustrated to the right in Figure '2- and shown; in Figures 3, and 6. f

This part of the machine comprises a pair of shafts 94: M16195, preferably inaligm ment with shafts. 28 and 29, respectively; the end of: shaft 94; being-shown in Figure 7 while shaft 95, can be seen in Figure. 2. The

shafts 94 and 95, areboth provided with" skeleton cylinders identical with cylinders 80, and 31; the cylinder. on shaft 95 being visible in Figure 2 at 96. The cylinder 96 on shaft 95 and the cylinder on shaft 9.4 are both-provided with grippers identical with the grippers'on cylinders 30 and 31-, 'previ ouslydescribed, so that specific description need not be again given; and; these grippers are tripped by similar mechanism and asrthe grippers on in a similar manner cylinder 3.1. V v Y The frame of the machineiis also provided with racks 97 and 98 containing thepamg phlets and wrapper-sheets, respectively,

which are set upv onedge as shown in Flg'ure 3 and intended to besucces'sively operated upon by the two. cylinders the racks being' so arranged that the pamphlets and wrapper sheets will move toward the cylinders as they are being successively withdrawn from,

the racks.

This and 5 he sac-hire, lik'ethex e inserting fend previously described, is also provided with the suction mechanism previously described, namely suction fingers identical with the finger 45 shown in Figure 8; the fingers to be operated by means of cams ::;and. vlevers arranged as previously described; with .the fingers connected by means of suitable tubingwith the suction or air-pump 52; the fingers being adapted 10 to contact with the upper edges of the adjacent pamphlets and wrapper sheets and cause them tobe drawn toward the respective cylinders as the fingers swing inwardly through the action of the cams and levers previously referred to.

The shafts94 and 95 are both provided with gears 99 and 100 (see Figure 3) which mesh with each other as shown, so that power may be transmitted from shaft 94 to shaft 95 and thus have the cylinders thereon rotate in unison, but of course, in opposite directions. Shaft 94 is adapted to be placed into operative relation with the power pulley 62 by means of a clutch 101 .(see Figure 7) which is operated by the control rod or lever 102 (see Figures 2 and 7). It is apparent from the construction shown in Figure 7 that both the tip inserting and the wrapping portions of the machine may be operated at the same time, or they may be separately operated by means of the two'clutches 87 and 102. The gear 100 on shaft 95 is also shown in mesh with a pinion 103 which is secured to a shaft 104 provided with a wiper element or blade 105 which is adapted to touch or sweep the front roller 106, which revolves through a portion of a glue or paste receptacle 107, see Figure 3. The wiper element or blade 105 is also adapted to slightly contact with the wrapper-sheets which are being carried by cylinder 96; the mechanism being so timed that the wiper element or blade 105 with the glue or paste will contact merely with'the marginal edge of each wrapper-sheet which is carried by the cylinder.

At a point beneath the cylinders mounted on shafts 9.4 and 95, the machine is provided with the frame-members 20 disposed transversely of the machine; the frame members being enlarged or bellied intermediate .of their ends, as shown in Figures 3 and 5, to provide bearing for a number of rollers of the rolling or wrapping mechanism now to be described. I

At a point in alignment with the downwardly fed pamphlets and wrapper-sheets that are being discharged in juxtaposition by the cylinders, are a pair of compression rollers 108., 108, see Figure 5, between which the pamphlet and wrapper'-sheet are forced to pfias's, as shown in dotted lines in F igure The: rollers 108 are driven by means of pinions 109 and 110, secured to the end of each roller; while pinion 109 in turn meshes with an idler 111, see Figures 2 and 3; the rollers being caused to rotate in opposite directions the same as the cylinders above.

At a point beneath the pressure rollers 108, I provide a sectional cylinder 112, which is composed of a permanent section or seg ment 113, suitably secured to the cross-members 20 of the machine frame, and two movable sections or segments 114 and 115; while a portion of the cylinder at a point beneath the compression rollers 108 is left open at 116 see Figure 5, adapted for the entrance of the pamphlet and wrapper-sheet. The section 114 is provided at its ends with end members 117, see Figure 6, the upper end whereof is pivoted at 118 to the crossmember or frame 20*, so as to permit the section 114 to swing outwardly into the position shown .in dotted lines in Figure 5. The section 115' is similar to section 114, being also provided with end members 119, which,

like members 117 of section 114, are pivoted at the upper ends at 120 to the framemembers 20 so as to permit section 115 also to swing outwardly away from section 114 into the position shown in dotted lines in Figure 5. Thefree edges of the movable sections 114 and 115. are preferably beveled so as'to provide a smooth joint at the meeting edges as shown at 121 in Figure 5.

The movable or swinging sections 114 and 115 are controlled by the two'short links 122, see Fgiure 3 which are pivotally secured to the sections 114and 115, respec tively, whilethe other ends are pivotallv secured to an end of a rod 123, the other end whereof is pivoted, to the end of a lever 124. The lever 124 is pivoted at 125 to the frame of the machine so as to be free to swing through a vertically disposed arc.

At a point intermediate of its ends and on the side toward cylinder 96, the lever 124 is provided with a roller. 126Qsee Figures 2 and 3; and roller 126 is adapted to be acted upon by a cam 127 which is secured to shaft As shaft 95 with cam 127 is rotated, the cam 127 will strike roller 126 and thus force lever 124 downwardly, causing rod 123 to force links 122 downwardly and induce them to spread apart at their lower ends, thereby forcing the sections 114 and 115 of the sectional'cylinderapart into the position shown in dotted lines in Figure 5, namely so as to open the cylinder and allow the contents to drop out.

At points circumferentially disposed about the cylinder, the frame of the machine and the end members 117 are provided with rotatably mounted shafts 128; all of which are provided with a plurality of friction rollers 129. The respective sections 113, 114 and 115 of the cylinder, at points coincident with the friction rollers, are provided with slots or openings 130 through which the peripheries of the friction rollers 129 are disposed; the rollers 129 being preferably of rubber or other friction inducing material.

The ends of shafts 128 are provided with pinions 131, which mesh with idlers 132, which are rotatably mounted at the points 133 in Figure 5. The pinion 131 at the top of the cylinder, adjacent the opening 116, is shown in mesh with pinion 110, of pressure roller 108, so that power is transmitted'to the pinions 131 on the shafts 128 disposed about the left side of the. cylinder,as viewed in Figures 3 and 5,-through the medium of the gear 100 on shaft 95 which w meshes with a pinion 13 1 secured to the stub-shaft on which idler 111 is secured idler 111, pinions 109, 110 and the intermeshing pinions and idlers 131 and 132, thus causing all of the friction rollers 129 to revolve, that are carried by cylinder sections 113 and 11 1.

In order'to transmit power to the friction rollers carried by cylinder-section 115, I provide an idler 135, suitably mounted on a portion of the cross-member 20 of the frame. This idler 135 is arranged in mesh with idler 111 (see Figure 3) and also with the pinion 131 secured to the shaft 128 atv the-upper pivotal, point of cylinder-section 115 and by means of an intervening idler 132 to the pinion 131 on the shaft 128' at the lower end of end member 119 of cylinder-section 115.

As is apparent from the construction, the pamphlet and wrapper-sheet (the latter having one of its marginal edges supplied with glue or paste by wiper 105) are jointly fed, by their respective cylinders, in proper relation to pressure rollers 108, which in turn cause them to pass down, as shown in dotted lines in Figure 5, into contact with the inner surface of cylinder-section 115. Withthe cylinders and pressure-rollers in operation. the various friction rollers 129 will also be rotated at a requisite speed, so that the "combined pamphlet and wrappersheet coming into contact with the friction rollers 129, will be caused to follow the inner circular surface of the sectional cylinder and thereby rolled into tubular form with the wrapper-sheet on the outside. In practice, the wrapper-sheet may be made of slightly greater width than the pamphlet so as to have a small portion of the wrappersheet extend beyond the pamphlet when the latter, with the wrapper-sheet has been rolled into tube-form; and the extended edge of the wrapper-sheet having been previously supplied with glue or paste by wiper element 105, will therefore be made to adhere to the portion of the sheet with which it is brought into overlapping relation.

The mechanism is so geared and timed that by the time the pamphlet and wrapper-sheet have been completely rolled, the cam 127 will acton the roller carried by lever 124e, causing the latter to oscillate, forcing rod 123 downwardly and thereby cause the cylinder-sections 11 1 and 115' to separate so as to allow the completely rolled and .wrapped pamphlet to drop out.

At a point beneath the wrapping mechanism, I provide suitable receiving mechanism, which is shown in the nature of an endless belt 136, disposed transversely of the machine and caused to rotate about suitable rollers 137 which may be driven by any suitable mechanism at the desired speed. As the wrapped pamphlets or magazines are discharged from the wrapping-cylinder they drop onto belt or carrier 136 and are cone veyed to the side of the machine where they may be readily gathered up, or allowed to fall into any suitable receptacle, preparatory to being addressed and mailed.

The lever 124 and therefore also wrap ping cylinder-sections 114i and 115 are re turned to normal and closed positions by means of a suitable spring 138, whereby lever 124, or rather roller 126 carried thereby is maintained in constant contact with the cam 127 on shaft 95, so that as the eccentrieportion of the cam 12? has passed the roller 126. the lever 124. will be in its raised or normal position shown in Figure 3.

As is evident from the construction shown and described, the tip inserting and wrapping mechanisms of the machine may be op erated at the sametime by throwing both clutches 87 andlOl into mesh with pulley 62 at the same time; or either mechanism may be separately operated, as required, by merely throwing the requisite clutch into position.

I have shown and described what I believe to be the simplest and best exemplification of my invention; but alterations may be made in certain details of the invention without, however, departing from the spirit of my invention.
